    摘要： A shape memory alloy (SMA) actuator includes an SMA element and a flexible outer coating or layer. The element is respectively activated by a heating source. The layer surrounds the element, and enhances the heat transfer characteristics of the element to increase the speed of the actuation cycle. The nominal geometry and/or thermal conductivity may be altered during an activation phase, and may include discrete elements oriented with respect to the element, and partially embedded in the layer. An end gripper assembly may be used to cause the layer to move in concert with the element during a phase transformation. An electro-mechanical system includes the cooling source and the actuator. A method includes connecting the actuator to a load, activating the element using the heating source, and deactivating the element using a cooling source or free/ambient air.

    摘要： A deformable bi-stable device includes an elastically deformable member having at least two stable configurations and capable of being deformed from a first stable configuration to a second stable configuration, the element passing through an unstable configuration as it is deformed from the first stable configuration to the second stable configuration, and a shape memory polymer layer on or in the elastically deformable member. A method of using this device includes heating the shape memory polymer to a temperature sufficient to reduce the modulus of the shape memory polymer, deforming the deformable member to move from one of the first and second stable configurations to another of the first and second stable configurations, and cooling the device to a temperature sufficient to increase the modulus of the shape memory polymer.

    摘要： A reconfigurable bi-stable device includes an elastically deformable panel laterally disposed between and connected to one or more mounting members directly or indirectly connected to opposing ends of the panel, with the panel maintained under compressive force along at least one vector extending between the opposing ends. The compressive force deforms the panel into a one of two stable deformed positions, with the device disposed such that the panel may be moved between each of the two stable deformed positions by application of manual force to one of two opposing faces of the panel. A first shape memory alloy (SMA) or piezo actuator member is connected to the panel, the actuator member being capable of moving the panel from a first one of the two stable deformed positions to a second one of the two stable deformed positions.
